F. S. Like New A Set of 12 Needle Nicholson Jewelry Files, Round handles, see photo'
If I didn't have 3 sets of these (one unused),I'd have already bought these.
You can deburr 60 degree thread form pins if you need to. You can also use the triangular file for modding tenons. Same goes for weight bolts.
They work VERY nice for deburring/chamfering ferrules,joint collars,if they aren't already countersunk. Tommy D.
